For those who have been wanting to try a distributed loading design using partial cathode follower action, but couldn't find a transformer available or affordable: the Elliptron! Just use a commonly available Ultra-linear configured transformer but wired up like a Circlotron. Except! - connect the output tube cathodes to the 40% taps. The primary center tap gets grounded like in the Circlotron topology and the plates still connect to the usual primary endpoints through separate floating power supplies. (Cathodes for a given tube connect to the 40% tap on the OPPOSITE side to its plate/pwr. connection) For a typical 40% tapped transformer, the result becomes 28.5% cathode follower action which is much easier to drive. ( .4/(1+.4) ) Suggest using two cheap dual bobbin isolation transformers with 117x2 secondaries in series for plate supplies to minimize common mode capacitance to ground. The Hammond 1650T output transformer with its low 1900 Ohm CT primary and UL taps is a good fit for this idea. Can make as a Modified UltraLinear (per N. Crowhurst) (see Glass Audio 3/96 page 20 ) if desired by just using a fixed screen voltage to ground.
